The features of F-Theta lenses, the values of the characteristics of the most common models are considered. The conditions for achieving the F-Theta law and the telecentric run of the main rays in the optical scheme of the lens are identified. A formula for the distortion required to provide a linear law, depending on the angle of the inclined beam of rays relative to the optical axisis given. The criteria for the permissible error of deviation from the exact compliance with the linear law are formulated. The relevance of the development of new optical systems for F-Theta lenses is justified.
